To all whom it may concern.-

Be it known that I, N ms Emu. Larson, a citizen of Sweden, and a resident of the borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Curtain-Poles, Brackets, and Clamps, of which the following is a specification. 7

This invention relates to devices for suspending curtains, portieres and draperies, and the object thereof is to provide im lements of this character which will, t simplify the hanging of the curtain or like article, and secondly, facilitate its adjustment both vertically and laterally, in such a manner that it can beeasily lengthened or shortened, spread out or gathered into folds, mounted close in or far out, and generally fitted to harmonize with the environment or to suit special occasions.

Referring to the drawing hereto annexed, which forms a part of this specification, and in which like numerals designate like elements wherever they occur, Figure 1 is a partial top view of the preferred form of the invention, portions thereof being in section. vFig. 2 is a front view of the same construction, partly broken and partly sectioned. Fig. 3 is a transversesection taken from the line 3-3 of Fig. 2, looking in either direction. Fig. 4 shows the same form of clamp as is illustrated in Figs. 1, 2

' and 3, but removed from the pole and indi- The said pole members are made of wood,

eating the opening device inserted between the jaws of the clamp. Fig. 5 is aface view of the construction shown in Fig. 4. Fig. 6 is a view similar to Fig. 4, but showing the clamp open. Fig. 7 is a side view, partly in section, of a modified form of clamp. Fig. 8 is a face View of the latter-named form of clamp; and Fig. 9 gives a rear view of the same.

The pole proper, as illustrated in Figs. 1, 2, and 3, consists of two parallel members 11 and 12, intended to be held at some distance apart one from the other, in order to maintain between them a vacant space 13, wherein the upper end of the curtain, portiere or. drapery, to be hung from the pole may be inserted, and slid edgewise after insertion. The numeral 14 represents, say, a curtain, to which reference will be made hereinafter to the exclusion of either portiere or drapery, to avoid useless repetitions.

preferably, in strips of equal length and thlckness, and segmental in cross section, the flat sides whereof are designed to face each other.

Suitable means are provided to join the members 11 and12'together at their opposite ends and at the same time to keep. them at the required distance apart. The said means comprise each a spherical head 15, a

cylindrical neck portion 16, and a tenon like reduced portion 17 all of which are either made in one piece or rigidly interconnected. The latter-named portion fits, as within a mortise, between the opposite fiat faces of the pole members 11, 12, at the ends thereof, and for that reason will be referred to hereinafter as the tenon. The said.

or less extent according to the relative thickness or tenuity of the latter.

A sleeve 18 serves to keep the members 11, 12, united to the said head, neck and tenon, at each end of the pole. The said sleeve is conveniently made of brass and fitted so that it will either cover the cylindrical neck 16 alone, or extend partly over the base of this neck 16 and partly over the adjacent ends of the pole members abutting thereupon. In the latter position, the sleeve operates to press the opposed ends ofthe said members against the tenon, in each instance, and to hold these parts firmly united with one another. A screw 19, driven into one side of the neck 16, and engaging a helical slot 20 in the sleeve 18, prevents longitudinal displacement of the latter otherwise than by rotation, thereby precluding accidental disengagement of the tenon from the contiguous ends of the pole members, at least under normal conditions. It will'be seen that in order to'disengage the said parts from one another, the said sleeve must be purposely rotated to shift it from the position illustrated in Fig. 1 to that represented in Fig. 2, through co-aotion of the screw 19. and helical slot 20.

The interval between the pole members aforesaid may further be maintained uniform by means of a two-pointed screw 21, located between the two members, one point of the screw being driven into the flat inner face of each member, as indicated at the right-hand Side of Fig. 1. By placing this screw centrally of the pole, it will lie exactly at the dividing line between a pair of curtains.

A simple form of bracket is provided at and for each .end of the pole, the same constituting an integral part of the invention.

Each bracket consists merely of a spacing block and means for fastening it both to the pole and to the wall, partition, molding, or other supporton which the pole is to be mounted. The numeral 22 designates the said spacing block, which may be of wood and is preferably made cylindrical as shown,

with a flange 23, designed to bear upon the support. The unflanged end of the block is hollowed out to receive the rear side of the spherical pole-head 15, which rests therein as at 24, Fig. 1. By reason of the dished o-r concaved recess (24) formed with the outer end of the said spacing block 22, the pole- 'head 15 is self adjustably seated therein even if the support to which the device is attached is out of alinement. A headless screw 25 is run axially through the block from its flanged end, and diametrically through the pole head lying thereagainst, both said block and said pole-head being suitably bored on a straight line for thatpurpose. The said screw 25, next to the point thereof, which is to be driven into the. support, has a shoulder 26, socketed or countersunk in the flanged end of the block. Thence the shank of 'the screw runs inwardly through the juxtaposed block and .pole-head and terminates in a recess 27 provided in the outer side of the latter. A

, nut 28 is in threaded engagement with the shank of the screw at this end and bears against a washer 29 interposed between it and the bottom wall of the said recess. The shoulder 26, nut 28 and washer 29, it will be seen, cooperate in holding the pole-head and 'gral with the pole-head. A plug 3O,v conformin in outline to the spherical head 15, is emp eyed to cover up the recess 27 and parts lying'within, thereby giving the polehead a smooth surface and normal appearance.

Each curtain is held at its upper edge or end, within the vacant space 13 between the separated members 11 and 12 of the pole, by means of two or more clamps, which may be of either of the forms illustrated in the drawings. The clamp shown in Figs. 1 to 6, inclusive, consists of a strip of spring metal doubled upon itself to. form a loop 31 and a pair of'jaws 32 extending out therefrom. The clamp represented by Figs. 7 to 9 is made of like material and ma similar manner, having also a loop 33 and jaws 34. With both forms of said clamps, the looped portion is considered as the upper end, which is designed to bear and slide upon theupper edges of the members 11- and 12 of the pole above described. These edges of said members are beveled off as shown at 35, 36,

in Figs. 1, 2 and 3, to aiford a better bearing and slideway for the said looped portion of either form of clamp. In both forms of clamps" also, the jaw portion is undulated, that the jaws may have a firmer hold or stronger grip on'the curtain, Wl'llCll is placed therebetween in the manner indicated inthe figures last named. A diamond-shaped opening 37 is provided between the jaws 32 and .the looped portion, in the form of clamp first above mentioned, for'the insertion of a key 38, with which these jaws can be spread apart to facilitate the operation of placing the curtain between them, or removing it.

In the second form of clamp mentioned above, the jaws are spaced from each other,

as required, through the agency of a screw 39 and nut 40, arranged to press on opposite sides of the clamp. The head of the screw is countersunk in the upper jaw, so to say, and lugs 41 of the latter are brought to bear on it, as shown in Figs. 7 and 8. As to the nut, it is embedded in the lower jaw, which also has lugs 42 bearing thereon, as indicated in Figs. 7 and 9. These lugs 41 and 42 are formed integral with the ribbed sides of the clamp, respectively. 43 and 44.

Having descrlbed my invention what-I desire to secure claim is:

1. A curtain pole composed of a pair of parallel separate members, independent one from the other, means for keeping them a constant distance apart, whereby a uniform open space extending all the way between by Letters Patent and their inner sides is provided, thereby affording a free passage for the insertion of the curtain from either top or bottom of the members while they are in a fixed position and for sliding it freely lengthwise between the pole members, means for holding the curtain while the latter is being adjusted, and other means extending at right angles from a wall or other primary support for detachably clamping the ends of the curtain carrying pole members in parallelism.

2. A curtain-pole comprising parallel I members, distinct from one another and means for holding the same a constant distance apart, thereby rendering the curtain independently movable and adjust-able between said members", said means including a head directly attached to a support, a neck extending therefrom, a flattened tenon'projecting centrally from said neck into the adapted to slide over opposed ends of the strips to hold the latter against the flattened portion of the neck.

4. In a curtain-pole, the combination with two pole members spaced a constant distance apart and kept in parallelism, of heads con stitllting supports for said members, each head having a neck With a flattened central portion, said pole members being detachably secured independent of each other to opposite sides of the flattened neck portion,

- a rotatable sleeve mounted on the neck and the neck said slot operating to move the sleeve endwise of the pole members.

A curtain-pole comprising two parallel independent members having a uniformly open space therebetween, a sphero-convex head therefor having a neck with a flattened portion lodged between said members to keep them a constant distance apart, ex-

ternal means for holding the ends of said pole members upon the flattened neck portion, a spacing block having a sphero-ooncave seat adapted to'receive said head'constituting a self-adjustable bracket for the united head and pole-members and means passing through said spacing block for holding the united elements to a suitable support.

6. In a curtain-pole, the combination of separate parallel members, a head adapted to keep said members in parallelism at the requisite distance apart to permit of a curtain being moved lengthwise therebetween, a spacing block hollowed out to receive a portion of said head, a headless screw passing through alined bores in said head and said block, said screw having one end designed for attachment to a suitable support and the other end concealed in said block, and means connected with the screw operating to press upon opposite sides of the spacing block and pole head.

7. In a curtain-pole, the combination with a pair of parallel independent members of substantially semi-circular cross section having an open space of uniform width between their inner sides, and means for holding the ends of said members apart upon a mutual support, said members having their upper corners beveled downwardly and inwardly, of one or more spring clamps having upper loo ed portions smoothly rounded both ways and adapted to slide on the beveled upper portions of said members, the jaws of said clamps passing entirely across and between the pole members and grasping the curtain by friction alone, and internal means between the'jaws whereby they may be opened to release the curtain, the opening means being concealed between the members.
